Rocker Reset Assembly With Deviating Element for Low-Friction Return
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of existing rocker devices is challenging due to the need for the reset spring, movable part, and rocker to be coaxial, leading to increased friction forces and difficulty in replacing the reset mechanism.
Innovation Solution
The rocker device includes a supporting base, a rocker with a pressing part, a deviating element with a reset assembly on one end, and a rotating shaft for pivotal connection, allowing the deviating element to reset without requiring coaxial alignment with the rocker.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reset spring, movable part, and rocker are arranged coaxially to achieve the return function, then the rocker can reset properly, but the assembly difficulty increases and friction force increases
Solution Approach 1:
The patent divides the reset mechanism into separate components: the reset spring and movable part are separated from the rocker, with the reset spring located in the supporting base rather than coaxial with the rocker. This segmentation allows independent assembly of each component, reducing assembly difficulty while maintaining the rocker's return function.
Solution Approach 2:
The patent introduces a movable part as an intermediary element between the reset spring and the rocker. The movable part transmits the reset force from the spring to the rocker, enabling the return function without requiring direct coaxial alignment between the spring and rocker, thus simplifying assembly.
2Reliability
If the reset spring, movable part, and rocker are arranged coaxially, then the rocker return is achieved, but the friction force between components increases
Solution Approach 1:
By separating the reset spring from the rocker's rotational path and locating it in the supporting base, the patent reduces the contact area and friction between the reset mechanism components and the rocker, while still achieving the return function through the movable part linkage.
3Reliability
If the reset mechanism is integrated coaxially with the rocker, then the return function is achieved, but the complexity of the device increases
Solution Approach 1:
The patent segments the reset mechanism into independent components located in different spatial positions (reset spring in the supporting base, movable part as a separate linkage), reducing structural complexity compared to a integrated coaxial design while maintaining the return function.
Solution Approach 2:
The patent relocates the reset spring from the axial dimension (coaxial with rocker) to a different spatial dimension (in the supporting base), changing the dimensional arrangement to simplify the overall device structure while preserving functionality.

AI summary
The present application provides a rocker device, the rocker device includes a supporting base, a rocker, a deviating element, and a reset assembly. The rocker is provided with a pressing part. The deviating element includes a first end and a second end opposite to each other, and the first end is in contact with the pressing part. The reset assembly is disposed on the second end. When the pressing part presses the first end of the deviating element, the second end of the deviating element deviates, and the reset assembly drives the second end of the deviating element to reset. The assembly of the rocker device in the present application is simple, reducing a frictional resistance between the deviating element and the supporting base, thereby improving usage experience.
